Dilatation of the rectum is often necessary to temporarily paralyze the anal sphincter before performing interventions on the rectum. The patient should be purged and the rectum washed out with soap and water prior to the procedure. General anesthesia is almost indispensable, as spinal anesthesia can also be useful for anal operations. In cases where a special dilator is unavailable, two thumbs are inserted back-to-back and stretched rhythmically until they touch the ischial tuberosities. Drainage tubes wrapped in iodoform gauze should be used post-operation to manage pain and prevent infection.

Operations for hemorrhoids involve careful cleansing, dilatation of the anus, and excision of pile tumors. General anesthesia is employed, followed by meticulous cleaning and dissection of the affected area. Sutures are placed in a manner that allows blood to flow downward, reducing pain and bleeding.

Operations for anal fistulas require the use of a grooved director to open the entire length of the tract. Diseased tissues are then curetted or cauterized, and gauze is packed until granulation repair is complete.

Paraphimosis treatment involves thorough cleansing, cocaine application, and gentle reduction of the foreskin. Measures to reduce inflammation must be employed after reduction.
Circumcision is an operation often performed on infants or adults under general anesthesia in children and local anesthesia in adults. The foreskin is incised along a line that ensures proper healing.
Key Takeaways
- Dilatation of the anal sphincter requires thorough preparation and general anesthesia.
- Hemorrhoid operations involve careful dissection and suturing to manage bleeding effectively.
- Fistula repairs require opening the entire tract and curettage or cauterization of diseased tissues.
Practical Tips
- Ensure proper patient preparation before any anal surgery procedure.
- Use general anesthesia for most procedures to ensure patient comfort and safety.
- Apply drainage tubes post-operation to manage pain and prevent infection.
Warnings & Risks
- Severe pain may occur after hemorrhoid operations, requiring morphine injections.
- Improper handling of paraphimosis can lead to severe complications such as gangrene or sloughing.
Modern Application
While the techniques described in this chapter are foundational and still relevant today, modern medical practices have advanced significantly. The use of local anesthesia has become more prevalent for certain procedures, reducing recovery times and risks associated with general anesthesia. However, understanding these historical methods remains crucial as they provide a basis for emergency care when specialized equipment or anesthetics may not be available.
Frequently Asked Questions
Q: What is the purpose of dilatation in anal surgery?
Dilatation temporarily paralyzes the anal sphincter, allowing easier access and intervention on the rectum. It can also help cure fissures.
Q: How should a patient prepare for an operation to remove hemorrhoids?
The bowel must be cleansed through purgation and lavage three days before surgery, followed by enemas until the day of the procedure.
Q: What is the recommended method for treating paraphimosis?
Thorough cleansing and cocaine application are used to numb the area. Gentle reduction of the foreskin should be performed with traction forward on the foreskin and pressure backward on the glans.
